And, no, this isn't the old scam about putting a big lens in front of an upside down 17" TV with cardboard and duct tape... This actually works. In fact, results are superior to many commercial projectors: more lumen and better rez.
That is a fascinating concept. Too much time rounding up stuff before you even begin to build though. It looks like it would be a fun hobby project.
I wonder about things like component video inputs and all the screen adjustment controls I get on a commercially available projector. I scanned the web site and couldn't find any real detail there.
That looks way cool. What skill level would be required to actually do one of those projects?
